SWINGING JACK FOR WlNDOW-SASHES.

SPECIFICATION forming part of Letters Patent No. 486,740, dated November 22, 1892.

Application filed June 22, 1892. Serial lie-437,575. (N0 model.)

To all whom, it ntay concern:

Be it known that I, VALENTINE SOHIRMER, of New York city, in the county and State of New York, have invented a new and useful Swinging Jack for Window-Sashes, of which the following is a full, clear, and exact description.

This invention relates to an improved device for the swinging support of windowsashes to facilitate cleansing the same, the object being to improve the construction of the sash-supporting jack shown in the patent issued to me May 31, 1892,476,081, which device consists of a cast-metal triangular frame provided with a handle-bar and pivot-support on the latter, as well as upon the side of the window-casement, whereby the jack or frame is adapted to carry both sashes of the window and swing them inwardly when these released sashes are hung upon the jack.

To this end mypresent invention consists in the peculiar construction and combination of parts, whereby the improved jack is made lighter and cheaper and is also rendered adjustable, so as to adapt it to engage fixtures on different windows, and thus be rendered more convenient in service, as is hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an inner side elevation of awindow-casement broken away at one side, window-sashes therein, the upper sash being lowered and opposite the lower sash, and the improved swinging jack loosely connected with the easement and supporting the sashes ready for an inward swinging movement. Fig. 2 is a vertical sectional view on the line 2 2in Fig. 1. Fig. 3 is a plan view in section on the line 3 3 in Fig. 1, showing the sashes swung inwardly on the jack. Fig. 4 isa plan view in section on the linedin Fig.1, showing the upper sash removed from the jack and located in appropriate grooves of the casement and the lower sash on the jack that is swung inwardly. Fig. 5 is a view showing an enlarged detached and broken detail of construction. Fig. 6 is a sectional view of another enlarged and broken detail, taken opposite the arrow 6 in Fig. 2. Fig. 7 is a plan view in section of the upper sash detached, taken on the line 7 7 inFig. 2. Fig. 8 is aplan view in section of the lower sash detached on the line 8 8 in Fig. 2. Fig. 9 is a side view of a modified form of the swinging jack and a lower sash connected therewith, the latter being indicated by dotted lines. Fig. 10 is a broken inner side view of the lower portion of a window-casement and a lower sash therein withtwo improved sashsupporting clip-plates and hanger-hooks in position, these latter-named parts being detached from the clip-plates that are affixed to the sash. Fig. 11 is a view in cross-section of the parts shown in Fig. 10 on the line 11 11 in said figure. Fig. 12 is an inner side view of a window-casement and alower sash broken away with the improved clip -plates and hanger-hooks in a locked condition on the sash. Fig. 13 is a transverse section of parts taken on the line 13 13 in Fig. 12. Fig. 14 is an inner side view of a window-casement, a lower and an upper sash, the improved clip- 7:, plates and hanger-hooks on the lower sashin a locked condition, and the improved jack shown broken and engaging the hanger-hooks. Fig. 15is a cross-section of parts on the line 15 15 in Fig. 14. Fig. 16 is a perspective view So of one of the improved hanger-hooks, and Fig. l7isa perspective view of one of the improved clip-plates detached.

To further an efficient action of the improvement, it is essential that the window-sash should be counterbalanced by cords and weights and also be adapted for convenient removal fromthe casement laterally. To this end the Window-casement and sash are by preference constructed and arranged as shown in the drawings, a brief description of which parts will be given to render the operation of the improvement clear.

A represents the window-casement, and B C the upper and lower sashes, respectively, 5 the latter being held to slide vertically in the casement by the cords a and weights 1), as indicated in Fig. l. The usual bead-strips c d and parting-strips c are provided for the upper sash of the window, which strips termi- 1oo nate below on a line with the lower edge of the upper sash when the latter is in normal, position.

In Fig. 3 it will be seen that the width be- .tween the vertical faces of the window-casement that are engaged by the lower sash is greater than similar faces on the easement whereon the upper sash slides, thereby producing shoulders at 0 that serve as guides for the lower sash when it is in place and also prevent the sash C from having frictional contact with the upper sash when reciprocated vertically within the easement.

The bead-strips d on the inner side of the window-casement below are continuations of the strips (1 and extend from the lower ends of the latter to the sub-sill A of the windowcasement A, having a hinged engagement with the latter, which will permit them to he swung inwardly and afford clearance for the lateral movement of the sash. There is a jointclosing strip (1 hinged upon the sub-sill A, that when folded toward the sash C will seal the crevice below said sash when it is lowered, said strip being readily removed to permit the sash to be swung inwardly if it is folded as shown in Fig. 2.

The improved sash-supportingjack in preferred form consists, in part, of a metal bar E, that is bent at e so as to project a limb on the same at an acute angle to the straight longer portion, as shown in Fig. 1, said limb having a joint e formed in it. The free end portion of the limb e, that projects beyond the joint 6, is longitudinally perforated and internally threaded to receive the threaded end portion of a stay-rod E, that is so proportioned in length as to project diagonally upward and near to one side of the casementA when in position. An adjustable hook-block g is adapted to slide on the stay-rod E and be secured at any desired point by a thumbscrew 9, and on the upper terminal of the stay-rod a hook it is formed that may be interlocked with an eye-plate h, which latter is inserted and secured in a recess formed in the stile of the window-casement, as represented in Fig. 1, such a plate being shown on each side of the easement. At the end of the jack-bar E that is opposite from the portion whereon the limb eis formed an enlargement 'i is produced, which is vertically perforated to receive a fulcrum-pin t", there being a bracket-block 2' provided that has a seat on the sub-sill A and through which the pin 1" is inserted and thence into the sub-sill when the jack is placed in position for use, a laterally-extending finger 2' on said bracketblock having engagement with a perforation in the stile of the easement, so as to sustain the block with the jack hung on it.

Two means for connecting the windowsashes B O with the jack are provided, each being well adapted to impose the Weight of the sashes on the jack and adapt the latter to sustain the sash when they are swung laterally during the cleansing process. The simplest form for these adj uncts'of the swinging jack is shown in Figs. 1, 2, and 8, consisting, essentially, of two hook-plates k, that are atfixed upon the lower transverse rail of the lower sash at a properdistance apart, and two other hook-plates m, which are affixed to the outer side of the same sash-rail and enter slots in the lower surface of the lower or meeting cross-rail of the upper sash, there being similar metal escutcheon-plates m attached to the rail named and properly apertured so as to receive the upwardly-bent ends of these hook-plates that are on outwardly-projecting portions of the same. (See Fig. 2.)

I When the window-sashes are to be cleaned, the sash-holding jack is first placed in position, as shown in Fig.1. Then the top sash B is lowered and the sash-cords a are drawn upon so as to afford slackness that will permit said cords to be rove upon the hook-block g and also to engage projections g g on the upper cross-rails of the sashes B 0, whereby the sash-weight on one side of the easement A will be maintained elevated and the upper edges of the sashes be held together, as indicated in Fig. 2. The act of lowering the upper sash B will cause it to engage with the hook ends of the plates m, so that both sashes will be hung upon the horizontal jack-bar E if this piece has been located within the hookplates 75, and may be together swung with the jack into the room lighted by the window.

After the exterior face of the upper sash B has been cleaned it may be released and slid upwardly in the easement, as indicated in Fig. 4. This will expose the outer side of the lower sash C, so that it may be renovated, and the jack can now be removed and the inner sides of the upper and lower sashes be cleaned readily.

It will be evident that if the dimensions of windows in a building vary somewhat and the vertical distance between the hook-plates 7a and eye-plate h be different in such windows the length of the stay-rod E can be altered by screwing it into or out of piece 6 on bar E,

and also that the hook-block g may be shifted to adapt it to suit different windows, which provision renders the improved jack more generally useful and dispenses with need for providing more than one jack for a building.

In Figs. 10 to 17, inclusive, another device for supporting the two window-sashes of a window upon the swinging jack is shown. These are employed in pairs, and each support is composed of two parts, one piece being a clip-plate n and the other part ahangerhook 0. The clip-plate 02 (shown plainly in Fig. 17) consists of atablet of metal provided with screw-holes to permit its screwed attachment upon the lower transverse rail of the lower sash Oand having two opposite hooked flanges a formed on its edges that are projected from the same side of the clip-plate. Above the flanges n a headed stud n is projected from the plate at. The hanger-hook 0 is formed of a single piece of metal bent at a right angle near its center of length, as shown in Fig. 16, one part being notched 0ppositely on the edges, as at 0, ot a length that will allow the part of the plate left standing between said notches to pass freely be tween the hooked flanges n of the clip-plate n. On the top of the notched member of the hanger-hook 0 this portion is bent to form a depending hook 0 and at a suitable distance from the latter a circular aperture 0 is formed,which is extended between the notches 0 as a slot. Upon the other member of the hanger-hook a portion near the end is bent at a right angle or parallel to the notched member, thus producing a detent-lip 0 When the described parts are to be used for attaching the sashes B C upon the jack-bar E, the lower sash is slightly elevated and the upper sash lowered. Then the hanger-hooks 0 are in pairs placed on the sub-sill A of the window-casement opposite the secured clip-plates n, and each piece 0 is slid over the stud n that its hole 0 is opposite. A sufiticient length is given to the hanger-hook members having the detent-lips o to permit these lips to loosely engage the outer lower edgeof the upper sash B whenthe latter is lowered upon the hanger-hooks. Both sashes are now slid upwardly a sufficient distance to allow the hook portions 0 to pass over the jack-bar E, and then the sashes are lowered to throw their weight mainly upon the jack. The cords a are now adjusted to slacken them and cause their engagement with the projections 9 g on the sashes, as before explained, which will render the sashes capable of swinging along with the jack.

The slightly-modified form of the sash-supporting jack shown in Fig. 9 has its bar E bent at one end to produce a hook 19, that loosely engages with an eye pon the stay-rod E, which latter is adapted forchange of length by a turnbuckle attachment 1", the other parts of the device being similar to what has already been described.

In the form of the jack just described it will be seen that the stay-rod may be detached from the other piece E when the device is not in use, and thus permit it to be packed away closely, while the other form allows the stay-rod to be folded on the bar E by reason of its hinged joint. e',-so that one style is the equivalent of the other in construction and service.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1.
